Mr. Solis: Ryan! necesito ver como esta el uso de recursos del servidor AIX

Ryan: Que información necesitas?

Mr. Solis: El uso del procesador!

Ryan: Ah!,… puedes usar el comando topas

Luego de un momento,…

Mr. Solis: Me sale “not found”
Ryan: Que raro

Ryan se acerca a la PC de Mr. Solis y observa atónitamente que Mr. Solis habia escrito en la linea de comandos:

# topass
ksh: topass:  not found.

Ryan: WTF!!!

They wanted to find all file names in the source code of “XYZ” application without dots in their names so they were looking for the easiest way to do this task in GNU/LiNUX.

I’ve never needed to do that kind of search so I’ve recommended to read find command man page and use regular expressions. At home, I’ve found an nice way to do this task:

modlost@optimus:~/tmp$ mkdir -p testdir/1/2/3
modlost@optimus:~/tmp$ touch testdir/1/withoutdots
modlost@optimus:~/tmp$ touch testdir/1/2/with.dot
modlost@optimus:~/tmp$ touch testdir/1/2/3/withoutdots
modlost@optimus:~/tmp$ find testdir -type f -regex '[^.]*'
testdir/1/2/3/withoutdots
testdir/1/withoutdots
